Abstract: Embodiments include systems and methods for electronic wallet verification. In an embodiment, a blockchain computer system for real-time electronic wallet verification includes a fraud prevention computer system. The fraud prevention computer system is configured to protect user privacy and includes a virtual machine (VM) with a blockchain oracle. The blockchain oracle is configured to bridge one or more off-chain compliance and privacy protection interfaces. The virtual machine (VM) is configured to decode, via a decoder, a first smart contract on a blockchain computer network. The first smart contract on the blockchain computer network, in response to receiving a compliance check request including an electronic wallet, is configured to verify the electronic wallet by dynamically querying the one or more off-chain compliance and privacy protection interfaces for the electronic wallet via the blockchain oracle.
